    Blaupunkt 40” TV 40/233I-GB weird lines like moire effect after reassembling

    Hello everyone,
    the backlight wasn't working and after some online research, i stripped the display (total nightmare) to find one led at fault.
    I bridged the faulty led and after i reassembled the TV, the background lighting works fine, but the screen got some strange lines.

    It's not visible, if you sit straight in front of it.
    But change the viewing angle and it gets annoying.

    What could be the cause of this? Did i broke the Display while reassembling?

    did you keep all the sheets behind the lcd in the same order?

      Thank you for your reply,

      I'm pretty sure, that i took them all out at once and the order should be right.
      But maybe i did a sloppy job with the plastic spacers underneath.

      I'll try to refit it later.

        Also maybe try cleaning and reseating the tcon ribbon cables if equipped and the make sure the lvds cable from tcon to mainboard is clean and secure.

          I did a cleaning of all relevant contacts with a fiberglass pen.


          at the moment i think:

          a) i bent the thick diffuser sheet too much while disassembling and broke it internally (possible?)

          b) i really messed up the order of the diffuser sheets
